Abstract:

Intercomparisons between flow stress, microhardness, and rosette size measurements for purified KCl single crystals, KClCa, KClSr, and KClxBrl-x mixed single crystals are made. A good correlation between the flow stress and inverse of the length of the dislocation rosette size was found for this crystal system. These results, along with the results of other investigators show that once a rosette size versus flow stress calibration has been made for a particular crystal system, the rosette size becomes a useful, simple, nearly nondestructive technique for determining the flow stress of a crystal.
